/* expected myStringOfString value: "\"Hello world\"" */

let myStringOfArray = javaScriptToString(["Hello", "World", ".", "How", "do", "you", "do", "?"]);
console.log(myStringOfArray);
/* expected myStringOfArray value: "[\"Hello\",\"World\",\".\",\"How\",\"do\",\"you\",\"do\",\"?\"]" */

let myObjectString = javaScriptToString({
    friend1: "Shurik",
    friend2: "Alex",
    friends: {
        friend3: 123456,
        friend4: {},
        friend5: ["Hola", "amigo"],
        friend6: () => {
            console.log("How you doing?");
        }
    }
});

console.log(myObjectString);
/* expected myObjectString value:
"{friend1: \"Shurik\",friend2: \"Alex\",friends: {friend3: 123456,friend4: {},friend5: [\"Hola\",\"amigo\"],friend6: () => {
            console.log(\"How you doing?\");
        }}}"
*/

let myFunctionString = javaScriptToString(function(a,b) {
  console.log("Just a function");
})

console.log(myFunctionString);
/* expected myFunctionString:
"function(a,b) {
  console.log(\"Just a function\");
}"
*/

Simple.prototype.show = function(){
  Simple.count++;
  console.log('title = ', this.title);
  console.log('count = ', Simple.count);
}
console.log(javaScriptToString(Simple));

/* Expected:

var x = [1,2,3];
x[0] = x;
console.log(javaScriptToString(x));
